' The primary object of my invention is to provide a device that will eliminate synchronous body vibrations in a motor vehicle.

It is another object of my invention to provide a device whereby friction is interposed between two parts of a motor vehicle to eliminate synchronous vibrations between said parts.

A further object of my invention is to dampen by friction the periodic vibrations of a body of a motor vehicle caused by the synchronizing of the body and other parts with the engine impulses.

With the above and other objects in view, 15 my invention consists in the arrangement, 'combination and construction of the various arts of my improved device, as described in the specification, claimed in my claims and shown in the accompanying drawings, 29 in which:

Fig. 1 is a vertical elevation of my improved device attached to a dash of a motor vehicle, the rear portion of an internal combustion engine being shown in section.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

To properly illustrate the manner in which my improved device is assembled in a motor vehicle, I have shown a section of a rear por- 30 tion of a conventional cylinder block of an internal combustion engine, having a cylinder head 11 secured thereto. The cylinder block 10 is positioned in front of a conventional dash 12 of an automobile body.

The head 11 is provided with conventional water passages 41, a combustion chamber 42 and a threaded opening 43 for a conventional spark plug not shown. The block 10 has a cylinder 44, an intake passage 45 leading into the combustion chamber 42, an exhaust passage 46, and a valve 47 positioned in the passage 45 by a stem 48 in a guide 49 and a spring 50. Suitable water passages 51 are formed in the block to cool the various parts thereof. A conventional piston 52 with a rod 53 is placed for reciprocation in the cylinder 44. Also secured to the block 10 is a conventional manifold 54 having a passage 55 connected'with the intake passage 45 and a passage 56 connected with the exhaust passa e46.

ositioned on the dash 12 is my improved dampener, in the construction of which I provide a housing 13 having the lower portion of one end 40 open as at 14. The housing 13 has a flanged edge 15 bearing against the dash 12 and is held in position by bolts 16, lock washers 17 and nuts 18. The bolts 16 extend through and project from the dash 10 and a plate 19 secured to the dash 12 by screws 20 has its ends 21.bent around a portion of the bolt heads 22 to prevent rotation of the bolts 16.

A plate 23 having a friction lining 24 secured on one side thereof by rivets 25 is placed in the housing 13 with the end portion 26 extending out of theopening 14.

The bolts 16 extend through the center of apertures 27 in the plate 23 and linin 24, leaving a space or clearance between the bolt, plate and lining. Coiled springs 28 having their upper coils bearing against theunder side ofthe housing 13 and their lower coils bearing against the outside of the plate 23, are positioned around the bolts 16 to hold the lining 24 against the dash 12.

The end portion 26 of the plate 23 has flanged sides 29 with aligned aperturestherein forming a yoke. Inserted in the yoke between the sides 29 is an eye portion 30 of a rod 31 that is secured by the bolt 32 and nut 33. The other end 35 of the rod 31 is fastened to the cylinder head 11 by a cylinder head stud 3,6 and nut 37 In the operation of my improved device when the engine 10 is running the vibratory movement thereof will be conveyed throu h the rod 31 to the plate 23 and lining 24. e lining 24 being held against the dash 12 by the springs 28 tends to move back and forth. The friction of the lining against the dash 12 will stop body movement and thus prevent the impulses of the engine from causing synchronous vibrations between the body and the engine. The pressure of the springs 28 may be varied as desired to adjust the pressure of the lining 24 against the dash 12 to produce the proper amount of friction to break up the engine vibrations.

The clearance of the apertures 27 around the bolt 16 is suflicient to prevent the bolt 16 coming in contact with the metal plate 23 and the lining 24. 1

Although I have shown my improved vibration dam ener placed between the dash and engine, desire it to be understood that my improved device may be used between any two parts of an automobile to a ply fraction to one of the parts, thereby eliminating synchronous vibrations in the parts.

It will be obvious that various chan s may be made in the arrangement, combination and construction of the various parts of my improved device without .departing from the spirit of my invention and it is myintention to cover by my claims such changes as may be reasonably included within the scope thereof.

What I claim is:
